Debug freertos_blinky

I tried to start working with the OM13071 LPCXpresso824-MAX Development board. I use LPCXpresso v8.2.2.

For the first tests I took the "lpcopen_3_01_lpcxpresso_nxp_lpcxpresso_824max.zip" code examples of the nxp website.

First I tested the periph_blinky Project. It works fine. I can build and debug this project.

Then I tried to use the freertos_blinky project. I can also build this one. But it is not possible to debug this project, because the debug Options are not active. You can see it in the picutre below.

How can I activate this debug function?

When I try to flash this program with the "Program Flash" Option. Then I need an .axf- file. But it ist not possible for me to build an .axf-file. Also when I change the artifact extensions in Properties -> C/C++ Build -> Settings -> Build Artifact.

Did anyone have the same problems?

What are my mistakes and what can I Change to build this freertos project?

I have seleceted this project freertos_blinky and I can also build this project in this "start here" view.

I also tested it with diffrent other projects and they all word very well. And I tested it with other freertos projects with other microcontrollers and it worked without any problems. But it was for me not possible to Change this projects for my microcontroller on the LPC824 board.
